Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...

Proteins PIF1 and PCNA gather at sites of DNA damage in SETX-deficient cells, indicating activation of the BIR repair system. LA JOLLA, CA—The DNA inside our cells is constantly being damaged, and one ...

Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a dangling ...

You can always be judged by your scars. This is the idea that sums up what researchers at Spanish National Cancer Research Centre (CNIO) claim is one of the new breakthroughs in basic and biomedical ...

Francesca Storici consults at Tessera Therapeutics. She has received funding from the National Institutes of Health and the National Science Foundation. Your DNA is continually damaged by sources both ...

Cancer’s strongest gene switches push DNA into damaging overdrive, creating repeated breaks and repairs that may fuel tumor ...

A research team led by Professor ZHAO Guoping at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has unveiled a crucial mechanism that helps regulate DNA damage repair, ...

The DNA of human cells consists of a sequence of about 3.1 billion building blocks. Cells go to great lengths to maintain the integrity of this vast store of information. They constantly untangle ...
